This video is a lecture on specific latent heat, which looks at the energy absorbed or emitted by a substance as it changes states (solid, liquid, or gas). The lecture discusses two equations that can be used to calculate the amount of...

In this video we will look at how force, mass, velocity and acceleration are all related. Remember that velocity is the speed in a particular direction - a vector quantity! To change the velocity of an object there needs to be a force...

This video is a lesson on solving multiplication and division word problems about mass by drawing pictures. It uses examples of Tyrone and Mike's mass to demonstrate how to carefully read and think about the information given in the word...

Students will explore the principles of motion, the basic concepts of speed and velocity and how speed and acceleration are calculated. Numerous examples of common occurrences illustrate the principles of motion. Other terminology...

Two kids walk through the woods discussing momentum. I mean, who wouldn’t?

How exactly does a seatbelt save lives? In this video we are going to learn about the forces acting on an object due to changes in momentum. All moving objects have momentum; a stationary object has a momentum of zero. We calculate...

Every moving object has momentum. This is the tendency of the object to keep moving in the same direction unless acted upon by an external force. You'll have a hard time trying to change the direction of movement of an object with a lot...

In this video you will about weight, force, mass and gravity. When it says 56 kilograms on your bathroom scales, what are you actually measuring? Well, if you said weight, like most people would, then you are sort-of wrong! Kilograms are...
